The French Jacobins were the first to realize the political potential of class resentment. Exploiting it, they conjured constant conspiracies by aristocrats and other enemies of the revolution: shortly before their fall they drafted legislation expropriating private wealth and had the unmistakable communistic implications. It was from the study of the French Revolution that its aftermath that Marx formulated the theory of class struggle as the dominant feature of history. In his theory, social antagonism was for the first time accorded moral legitimacy: hate, which Judaism condemned as self-destructive, and Christianity (in the guise of anger) treated as one of the cardinal sins, was made into a virtue.

Within a month of taking control of the German government, the Nazis suspended constitutional guarantees of the inviolability of private property. Property was to be respected, but only as long as the owner used it for the benefit of the nation and state: in the words of a Nazi theorist, ‘[P]roperty was . . . no longer a private affair but a kind of State concession, limited by the condition that it be put to ‘correct’ use.’

One channel for transmitting Communist models to the Nazi movement were right-wing intellectuals with a left-wing bent close to Hitler, known as the ‘National Bolsheviks.’ Their chief theoreticians, Joseph Goebbels and Otto Strasser, greatly impressed by Bolshevik successes in Russia, wanted Germany to help Soviet Russia build up her economy in return for her political support against France and England.
